Re: Borate-ing my pool.

If you are using borax and muriatic acid, I would wait at least four hours after adding borates and then double check the PH right before swimming. As long as the PH is between 7.2 and 7.8, and all the usual things are fine (clear water & some chlorine) you are fine to swim.

Is this normal? I should add more Muriatic acid and start aerating?
If so how can I aerate in a Intex type pool?

Water looks great. Cant wait for daylight to see the real spark.
The pool is 3 weeks old . Water looked not very good in the beginning.
I followed your site advise step by step and it works.
I love my pool now. Vacuuming the bottom of the pool, cleaning the filter cartridge
daily is my everyday chore. Yes the filter builds up with pollen/dust/dead algae/rust/bugs
and who knows what in 24 h-rs. Cleaning it every single day helps to make my water clear.
Probably I have to upgrade the pump and filter to a better one in near future .
Which one ?

Thank you for your views and comments in advance.
Pictures by tomorrow.

Re: Borate-ing my pool.

This isn't really what you are asking about, but TC can't be lower than FC. Something is going wrong in your testing there. TC = FC + CC. CC can't be lower then zero, so TC must be equal to or higher than FC.

Give things longer to mix, ideally a full two days, before worrying about PH and TA too much. If you keep your PH between 7.2 and 7.5 for a while, the TA will come down. This will take a while, but I don't see any need to rush.

I suggest getting a small sand filter. They are easy to care for and much better than the Intex filters.

The Intex 2,500 GPH pump is alright. Your pool is relatively small, so you can probably stick with that pump without any problems.

Their recommendation was to put in 2lb of pH down
and 1 lb of cyan uric acid and 10 lb of Calcium Hardness knowing that is a vinyl pool.
I start to wander.
Last time I run a test with them CYA was 14 (even so it had already 1.5 lb of Cyan uric acid ) after adding additional 1,5 lb Cyan uric acid it jumped only to 26. Measurement was done after 1 week of adding the acid. I figured it is something wrong and left for a second(third) opinion.
I cant believe after mixing 3 lb of Cyan uric acid CYA level to be that low.
They mentioned Phosphates also.

Store #1 and #2 use identical Pinpoint Computerized water Analysis system. Results are very different on TH and CYA. Who to believe?
A TF-100 probably is the best which I don't have it yet .
By the way my pool is sparking clear,blueish,shiny and inviting .
